Overview
The Microsemi 1N5386E3/TR8 is a silicon Zener diode with a nominal voltage of 180V and a maximum power dissipation of 5.0 watts at 25°C. It features an axial-lead T-18 plastic package, unidirectional polarity, and RoHS compliance indicated by the e3 suffix. The device operates within a temperature range of -65°C to +150°C and includes a TR8 tape-and-reel option for automated assembly.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead mounting terminals suitable for various board configurations
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement equipment
Procurement Notes
Verify the specific suffix configuration against the datasheet to confirm tolerance and packaging details. Ensure the ordering part number matches the required voltage tolerance and reel specifications. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.
Selection Notes
Select this component for applications requiring a 180V Zener reference with 5W power handling capability. Consider the thermal resistance and derating curves when designing heat sinking solutions. Verify that the axial lead form factor fits the mechanical constraints of the target PCB layout.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options defined by suffix letters. The e3 suffix denotes RoHS compliant manufacturing.
Replacement Considerations
Equivalent parts include other 1N5386 variants with different suffixes for tolerance or screening levels. Cross-reference with military equivalents like MV1N5386D for enhanced screening requirements.
